Hello all. To start out with I am an amateur photographer looking to make my step into the world of DSLRs. I have a big trip to Honduras coming up over the summer where I will be spending two weeks in the rainforest with a research conservation group documenting the local species in an area of the cloud forest which has not yet been explored. I am looking at this as an opportunity to be able to take some unbelievable pictures of some awesome wildlife and being that I have until July I think I will be able to sufficiently play with the camera enough to get decent with it. I have been at the Pentax K10D and the Canons and Nikons of similar prices like the rebel xti. I really like the Pentax for the fact that it has the weather seals within the camera which I feel in the rainforest will really protect it but I know that most wildlife photographers tend to use Canon or Nikon. I know that I will be getting more opportunites to travel to places like this in the future and really intend to take this hobby as far as I can. Should I be limiting myself to the Pentax for the weather seal reason? I really like availability of lenses for the Canons and Nikons as compared to the Pentax which sometimes seem hard to find. As I had stated I will be doing predominantly wildlife and landscape photography so if you could all lend your advice as to what camera I should be getting it will be greatly appreciated.
